From 1d1d223aa3b37c34271aefc2706340d0843bfcb2 Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Fri, 4 Oct 2024 17:41:21 +0200 Subject: rust: alloc: implement `IntoIterator` for `Vec` Implement `IntoIterator` for `Vec`, `Vec`'s `IntoIter` type, as well as `Iterator` for `IntoIter`. `Vec::into_iter` disassembles the `Vec` into its raw parts; additionally, `IntoIter` keeps track of a separate pointer, which is incremented correspondingly as the iterator advances, while the length, or the count of elements, is decremented. This also means that `IntoIter` takes the ownership of the backing buffer and is responsible to drop the remaining elements and free the backing buffer, if it's dropped.
